网络家庭兴起的伦理基础及其社会影响

网络家庭以夫妻生活的无性化、夫妻关系的非对偶性、夫妻性别的可转换性和现实人伦关系的消匿等四大特征兴起于现代社会.其兴起的社会根源在于家庭功能的弱化、道德观念的宽容性增加和网络技术能力的增进.其中交织着网络空间的扩张与社会交往的挤压、心理压力的剧增与情感宣泄的不畅、婚姻需求的发展与现实条件的匮乏三大矛盾.网络家庭的兴起造成了家庭观念的变异、婚姻行为的变化和现实家庭的危机三大影响.     

Repetition blindness is immune to the central bottleneck

Theattentional blink (AB) andrepetition blindness (RB) phenomena refer to subjects’ impaired ability to detect the second of two different (AB) or identical (RB) target stimuli in a rapid serial visual presentation stream if they appear within 500 msec of one another. Despite the fact that the AB reveals a failure of conscious visual perception, it is at least partly due to limitations at central stages of information processing. Do all attentional limits to conscious perception have their locus at this central bottleneck? To address this question, here we investigated whether RB is affected by online response selection, a cognitive operation that requires central processing. The results indicate that, unlike the AB, RB does not result from central resource limitations. Evidently, temporal attentional limits to conscious perception can occur at multiple stages of information processing.     

Alteration of cingulate long-term plasticity and behavioral sensitization to inflammation by environmental enrichment

Exposure to an enriched environment (EE) has been shown to induce cortical plasticity. Considerable amount of research is focused on the effects of EE in the hippocampus; however, effects of EE on other brain regions and the mechanisms involved are not well known. To investigate this, we induced cortical plasticity by placing mice in an EE for one month and measured the effects of EE in the anterior cingulate cortex (ACC). Here, we show that EE enhanced the expression of the plasticity gene, egr-1, in the ACC of EE animals accompanied by enhanced cingulate long-term potentiation (LTP) and decreased cingulate long-term depression (LTD). The increased NMDA receptor NR2B/NR2A subunits current ratio is associated with the plasticity seen in the ACC while total protein levels remain unchanged. Furthermore, behavioral experiments show that these mice exposed to EE demonstrate enhanced responses to acute and long-term inflammation. Our findings suggest that exposure to EE alters physiological properties within the ACC which results in enhanced responses to inflammation.     

祛弱权:生命伦理学的人权基础

没有任何一个人始终处在坚韧性状态,每一个人都不可避免地时刻处在脆弱性状态.因此,祛除普遍的脆弱性的价值诉求在道德实践中就转化为作为人权的祛弱权.生命伦理学以祛弱权为其人权基础,也就成了有根的伦理学.     

The attentional blink: A review of data and theory

Under conditions of rapid serial visual presentation, subjects display a reduced ability to report the second of two targets(Target2; T2) in a stream of distractors if it appearswithin200-500 msec of Target 1 (Tl). This effect. known as the attentional blink(AB),has been central in characterizing the limits of humans’ ability to consciously perceive stimuli distributed across time. Here, we review theoretical accounts of the AB and examine how they explain key findings in the literature. We conclude that the AB arises from attentional demands of Tl for selection, working memory encoding, episodic registration,and response selection, which prevents this high-level central resource from being applied to T2 at shortT1-T2 lags. Tl processing also transiently impairs the redeployment of these attentional resources to subsequent targets and the inhibition of distractors that appear in close temporal proximity to T2. Although these findings are consistent with a multifactorial account of the AB,they can also be largely explained by assuming that the activation of these multiple processes depends on a common capacity-limited attentional process for selecting behaviorally relevant events presented among temporally distributed distractors. Thus, at its core, the attentional blink may ultimately reveal the temporal limits of the deployment of selective attention.     

Modeling Customer Loyalty from an Integrative Perspective of Self-Determination Theory and Expectation–Confirmation Theory

Purpose  This research conceptualizes and tests an integrative model of customer loyalty by linking two important theories: expectation–confirmation theory and self-determination theory. Design/Methodology/Approach  The model is examined using data obtained from 207 part-time students who have encountered the service of a skincare and beauty salon in Taiwan. These students work as full-time professionals in a variety of industries during the daytime and are financially independent for their daily consumption. Findings  The empirical results of this study indicate that loyalty is positively influenced by both intrinsic regulation and identified regulation, while introjected regulation and external regulation are insignificantly related to loyalty. Affected positively by service expectation and service confirmation, satisfaction has positive influences on all four dimensions of self-determined motivation—namely, intrinsic regulation, identified regulation, introjected regulation, and external regulation. Implications  The findings of this study show that the proposed model helps to learn about loyalty formation and its mediating mechanism in service contexts. Intrinsic regulation and identified regulation may be applied as two potential checkpoints for management to learn the actual status of customer loyalty based on a constant service quality offered by the service provider. Originality/Value  This study is one of the earliest to integrate expectation–confirmation theory and self-determination theory to explore loyalty. Besides, this study transplants the traditional application of self-determination theory from educational service to commercial service in general so that efficient strategies can be made for boosting loyalty.     

利多卡因凝胶在手术室麻醉诱导后留置尿管中的应用

分析手术室麻醉诱导后留置尿管产生尿路疼痛等不良反应的原因,探讨利多卡因凝胶在克服上述反应方面的作用及其他预防措施。采用方便取样将70例留置尿管的患者分为试验组和对照组,麻醉诱导后试验组在尿管上涂抹利多卡因凝胶（0．5ml／cm）后再按常规操作插管;对照组以石蜡油为润滑剂按常规操作留置尿管。比较两组患者心率、血压情况及躁动、疼痛评分。结果提示麻醉诱导后留置尿管可以有效减轻患者清醒状态下置管引起的尿路疼痛等问题,但不能避免患者苏醒期出现上述反应;使用利多卡因凝胶可有效预防患者苏醒期出现的尿路疼痛及其它不良反应,增加患者的舒适度。     

Separation and divergence: The untold story of James Robertson's and John Bowlby's theoretical dispute on mother–child separation

The work of Robertson and Bowlby is generally seen as complementary, Robertson being the practically oriented observer and Bowlby focusing on theoretical explanations for Robertson's observations. The authors add to this picture an “untold story” of the collaboration between Robertson and Bowlby: the dispute between the two men that arose in the 1960s about the corollaries of separation and the ensuing personal animosity. On the basis of unique archival materials, this until now little known aspect of the history of attachment theory is extensively documented. The deteriorating relationship between Robertson and Bowlby is described against the background of different currents in psychoanalysis in Britain in the interbellum. © 2009 Wiley Periodicals, Inc.

Identifying Variables Responsible for Data not Missing at Random

When data are not missing at random (NMAR), maximum likelihood (ML) procedure will not generate consistent parameter estimates unless the missing data mechanism is correctly modeled. Understanding NMAR mechanism in a data set would allow one to better use the ML methodology. A survey or questionnaire may contain many items; certain items may be responsible for NMAR values in other items. The paper develops statistical procedures to identify the responsible items. By comparing ML estimates (MLE), statistics are developed to test whether the MLEs are changed when excluding items. The items that cause a significant change of the MLEs are responsible for the NMAR mechanism. Normal distribution is used for obtaining the MLEs; a sandwich-type covariance matrix is used to account for distribution violations. The class of nonnormal distributions within which the procedure is valid is provided. Both saturated and structural models are considered. Effect sizes are also defined and studied. The results indicate that more missing data in a sample does not necessarily imply more significant test statistics due to smaller effect sizes. Knowing the true population means and covariances or the parameter values in structural equation models may not make things easier either.
